To aZZ whom it may concern.-

Be it known that I, WILLIAM M. CANFIELD, of Philadelphia, county ofPhiladelphia, State of Pennsylvania, have invented a new and ImprovedLubricating Compound; and I do hereby declare that the following is afull, clear, and exact description of the ingredients and proportionsused in preparing the same.

To produce my compound,I employ tallow, myrtle-Wax, Brazilianwax,beeswax, Japanese wax, German black-lead, American graphite, andasbestus, all combined, or portions of these articles combined, as maybe desired, and as will be hereinafter described.

To produce one form of the compound, I take of tallow, four (4) pounds;of myrtle-wax, one-quarter (i) of a pound; of Brazilian wax, one-quarter(t) of a pound; of beeswax, onequarter of a pound; of Japanese Wax,onequarter (t) of apound; of German black-lead, one and one-half (1%)pound; of American graphite, one and one -half (1%) pound; of asbestus,one and one-half (1%) pound.

Another form of the compound is produced by taking of American graphite,four and a half (4%) pounds; of myrtle-wax, one-quarterfi-l of a pound;of tallow, four (4) pounds; of beeswax, one-quarter (t) of a pound; ofBrazilian wax, one-quarter (3;) of a pound.

A third form of the compound is prepared by using four and one-half (4%)pounds of German black-lead; one and one-half (1%) pound of asbestus;one-quarter t) of a pound of J apanese wax; one-quarter (i) of a poundof beeswax, and four (4) pounds of tallow.

Any one of the formulas above described will producealubricatingcompound for steam and hydraulic packing that will prevent cutting ofthe metal where the packing is applied, and at the same time render thepacking pliable,

also impervious to the steam or water, and cause it (the packing) topossess great durability.

I do not wish to limit myself to the exact proportions as set forth, asmore or less of each of the ingredients enumerated can be used and thesame result accomplished.

Having thus described my invention,wl1at I claim, and desire to secureby Letters Patent, 1s
